“More than 14 million devices are already running Microsoft’s Windows 10 after its global launch on Wednesday, but it’s unclear how many of their users read the company’s Privacy Policy and Service Agreement before downloading. Tucked away in the 45 pages’ worth of terms and conditions (effective August 1) is a substantial power grab: The company is collecting data on much of what you do while using its new software.

From the moment an account is created, Microsoft begins watching. The company saves customers’ basic information—name, contact details, passwords, demographic data and credit card specifics —but it also digs a bit deeper.

Other information Microsoft saves includes Bing search queries and conversations with the new digital personal assistant Cortana; contents of private communications such as email; websites and apps visited (including features accessed and length of time used); and contents of private folders. Furthermore, “your typed and handwritten words are collected,” the Privacy Statement says, which many online observers liken to a keylogger. Microsoft says they collect the information “to provide you a personalized user dictionary, help you type and write on your device with better character recognition, and provide you with text suggestions as you type or write.”

All this information doesn’t necessarily remain with just Microsoft. The company says it uses the data collected for three purposes: to provide and improve its services; to send customers personalized promotions; and to display targeted advertising, which sometimes requires the information be shared with third parties. Microsoft mentions that though it assigns each customer a unique advertising ID, which is fed data during computer usage, it “does not use what you say in email, chat, video calls or voice mail, or your documents, photos or other personal files to target ads to you.” It makes no such promise for its other stated data collection purposes.

Though possibly surprising to some, the company’s data collection practices fit within the industry’s new normal. Google’s Privacy Terms, for instance, show that the tech giant is also analyzing the content of users’ emails to provide a better, more personalized product, it claims. And as The Guardian points out, “Both Siri and Google Now require access to the user’s personal information to personalise responses, while both Apple and Google offer developers the ability to deliver personalised ads to users based on information such as app installs.””
